. IMPROVEMENT IN MACHINE FOR J'OINTING- BAla2-RE1'.\ST.A.V'ES.v

lllfhe Schedule referred to in these Letters Patent and making part of the same.

' To all whomfit 'may concern..-

Be it known that I, HARRY A. ORossLnY, of Cleveland, in the county of Cuyahoga, and State of Ohio, .have invented certain new and useful Improvements in Stave-Jointing Machines; and the following isa full, clear,v andexact. description ofthe same, refer- Vcutting-bits.

The object of my inventionis to joint stares for casks truly, so that there will be the same proportional taper at both ends, whether the staves be wider narrow, the number more or-less, required to complete the circle of the cask; the bilge will be uniformly the 's'ame, so that'the caslis will gauge alike, or more uniformly than those ordinarily made.

My invention consists in the mechanism for adjusting and graduating the line of the shafts on which the revolving cutter-flanges are secured, so that the position of their faces are varied from andto a more' or less direct line, lin proportion to the width of the staves being jointed; also, in the construction of the cutter-flanges or wheels, they being so formed and arranged in relation to each other, that they are made to cut with` a drawing stroke, from the centre of thev stave, in opposite directions with the grain of the wood, thereby insuring a perfectly smooth and uniform joint.

'To enable others to make and use my improved stave-jointing machine, I will describe it more fully, marked thereon.

A is the frame of the machine, which frame should be substantially constructed, to resist the vibration of the parts.

On the front or the working side, the top timber A' is made in two parts, leaving a space, B, in the frame, for the mechanism to operate, on which the sta-ves a are placed, to be jointed. v

The cutting-flanges C C are formed with four arms, c cc c, the outer ends being semicircular, to t in the semicircles e e e e, of each other, so that the bits or cutters b b b b, will overlap or reach by the central portion of the stave a, taking a drawing-cut in opposite directions.

The cutting-flanges G O are secured to horizontal shafts D D, which may be connected by cog-gear wheels F F, so that one shaft will drive the other, there being a belt-pulley, E, secured to either one of the shafts D.

The journals on the face ends of the shafts run in boxes d d, which are pivoted to the top ofthe iamcpieces A', so as to allow the rear ends of the shafts D D, in their sliding journal-boxes g g, to move laterally to and from each other, at the pleasure of the operator, and thereby change the angle or position of their faces, as required by the width of the staves being jointed.

lhe mechanism for effecting this movement of the cutting-disks or flanges C C is very simple, yet very peculiar, and consists lof the following:

To the sliding journal-boxes g g, are 'connectinglinks f f, with sliding boxes fitted to ,work on a rightand-left screw," h, in the top of a disk, H, on an upright shaft, G, in the centre of the rear portion of the frame, between the rear ends of the shafts D D.

lhe vertical shaft G is provided with an arm, fi, to

which a bar, I, connects with a rock-shaft, K, which Y jointed, are supported on two standards, m m, in the rock-shaft K, in such a position as to make the bevel of the staves theproper radins of the cask, so that the joints will be perfectly tight, both inside and outside. 4 The rest M is provided with hubs or stops, a n, which are held up in. position to hold the stave ou the rest by helical springs o o, which will allow the hubs n n to be pressed down, 'to admit the staves being placed on and taken on. v

What I claim as my iuvention,and desire to secure by Letters Patent, is

1. Thecombinatiou of the mechanism herein described, to wit, the sliding journal-boxes g g, connecting-links f f, with sliding boxes, to work on the rightand-left screw h, the disk H, and shaft G, for adjusting the cutting-flanges or disks C C to a more or less di-` rect line, for jointing staves, when operating in the manner and for the purpose specified.

2. The cutting-disks C C, constructed, arranged, and operating in the manner and for the purposes C. H. GLAYCOT, A. '.D. HEI/run.
